Rosie violence and depression

So many people that receive violence from their parents growing up with the mentality that the abuse and violence is something normal, but  I don't believe that is  Rosie's case. She had a good hearth and i do believe that she did not hit the girl with purpose, thankfully in that moment she realize that she did not want  to made the same mistakes of her mother or worst be like her. Moreover, that is why she fell into an instant depression because she regret it.
